Police on Claudia Lawrence's disappearance 4 years on

We have not forgotten Claudia. We have put a tremendous amount of effort into unravelling the events of 18 and 19 March 2009.

Her silver Samsung D900 mobile phone and blue and grey Karrimor Spectre 10 rucksack remain unaccounted for. As with many investigations one vital piece of information could make the difference and enable us to complete the picture and finally resolve Claudia’s disappearance.

All anniversaries and significant dates magnify the impact of her absence. Our thoughts are with her family as this milestone is reached.

– Detective Inspector Adrian Gathercole, North Yorkshire Police
